Vertical indoor unit installed in 2018 with bottom draw return and hardwood flooring. Client moved into the home last June. The system has never been maintained or serviced since moving in. Client concerned about water pouring onto floor beneath the unit each time it meets temperature or shuts off. Performed diagnostic and found very impacted drain line and impacted internal drain pan. Also found several fittings which were unglued. Cleared drain line and removed sludge from internal drain pan. Applied PVC glue and sealed all fittings. Extended external drain to keep it from affecting side of the house. Tested to insure accuracy and system draining well upon departure. Waived diagnostic with service repair per office. Total collected $168. Paid with Visa. Job complete.
